Compact in-line refractometer
NEW – Now with extended measuring range!
Compact in-line refractometer iPR Compact² with very short response time for continuous measurement and real-time process control with one analogue data output.
The iPR Compact² allows the inline, real-time refractive index, Brix or concentration measurement to monitor and control the concentration of dissolved solids in solution or liquids in process. The compact stainless steel measuring head with YAG Prism is equipped with an integrated electronic for direct connection to supervisory system or PC.
- Precise, fast and reliable
- Permanent real-time concentration measurement
- Compact sensor
- Galvanic isolated 4 – 20 mA output
- Excellent price-performance ratio
